External Siren Telmor TSZ-4D — outdoor alarm siren, model TSZ-4D

The Telmor TSZ-4D external siren is an outdoor alarm siren designed for integration with security and alarm systems. Built for perimeter signaling, it provides both audible and visual alerts to indicate intruder alarms and system status. The TSZ-4D is suitable for installation on residential and commercial buildings where reliable external notification is required and is compatible with standard alarm control panels and detectors.

Advantages

The TSZ-4D offers a combination of loud acoustic output and visible flashing to ensure events are noticeable at a distance. Its enclosure is designed for outdoor use, protecting internal components from weather and allowing continuous operation in typical external conditions. Installation is straightforward with common wiring connections for power and alarm input, enabling quick integration into existing alarm systems. The unit's design supports clear signaling of alarm states and contributes to perimeter deterrence.

Suitable for

• Perimeter protection of residential properties
• Exterior notification for small and medium commercial premises
• Integration with wired alarm control panels and detectors
• Situations requiring both audible and visual external alerts

Key specifications

• Outdoor-rated enclosure suitable for external mounting
• Combined audible siren and visual strobe output
• Wired power and alarm input connections compatible with standard alarm panels
• Designed for perimeter and external warning applications
• Materials and finish suitable for exposure to weather conditions

How to use

Mount the siren on an external wall or mast at a location that provides clear sound propagation and visible line-of-sight for the strobe. Connect the unit to the alarm control panel following the panel manufacturer's wiring diagram: provide the required supply voltage and wire the alarm input/output terminals so the panel can trigger the siren during alarm events. Verify polarity and secure cable entries to maintain enclosure weather protection. After installation, test the siren function from the control panel to confirm audible and visual signaling and adjust mounting position if necessary for optimal coverage.

Usage recommendations

Position the TSZ-4D at a height that avoids vandalism but preserves sound and light dispersion; routinely inspect mounting hardware and cable glands for integrity and clean the strobe cover to maintain visibility. Use within the compatible voltage and wiring limits specified by the alarm control panel manufacturer.
